E3 - Racing Spark Plugs

E3 non-resistor, cold heat range Racing Spark Plugs are designed for a variety of racing applications. E3 racing plugs contain a patented DiamondFire ground electrode, that is secured to the shell with two legs. This produces excellent heat transfer, with added stability to the side wire in high compression engines. E3's DiamondFire ground electrode increases power, reduces fuel consumption and improves hydrocarbon emissions in long-term use. The E3 ground electrode and full-size center electrode produce optimal performance and long-term durability.E3 Spark Plugs are sold individually.
